Description

The present invention relates to agriculture and can be used for cooking soft waste slaughter animals in meat processing enterprises.

Known open biconical resonators used to increase the radiation quality factor [1]. Visible radiation is observed from the open end of the resonator. In order to increase the radiation quality, open resonators are used, the cross section of which decreases from the center to the edges. In the middle of such resonators, there are waves whose constant propagation decreases in the case of distance from the center of the resonator. When the diameter of the open end of the resonator reaches certain limiting values, which can be characterized by the value of half the diameter of the base of the conical components of the resonator, the Q-factor of the resonator is significantly reduced and its use loses meaning [1].

Taking into account such well-known provisions, we are developing a microwave installation, where the working chamber is a sphere joined by open conical resonators, which allow unloading finished products in a continuous mode and ensure radio-tightness.

An object of the invention is to ensure the radio-tightness of the microwave installation for the heat treatment of raw materials in continuous mode.

The technical result is achieved by the fact that the microwave installation with conical resonators for heat treatment of non-food waste of animal origin contains inside a spherical shielding housing with a loading pipe, along a vertical axis coaxially dielectric disk with guide vanes and pushers mounted on the shaft of the electric drive,

moreover, circular conical resonators are docked uniformly along the perimeter of the shielding body, the axes of which coincide with the radial axes of the spherical shielding body and inside which the dielectric guide trays with stop elements and with radio-coated springs are coaxially mounted,

while the magnetrons of microwave generators are installed at the joints of a spherical body and circular conical resonators with discharge openings on the tops, with a diameter less than a quarter of the wavelength,

and the diameter of the spherical shielding body and the parameters of the conical resonators are matched with the wavelength.

Microwave installation with conical resonators for heat treatment of non-food waste of animal origin (Fig. 1-5) includes:

spherical shielding housing 1; magnetrons 2 microwave generators; circular conical resonators (with a circular base) 3; dielectric guide trays 4; discharge hole 5; springs with radio absorbing coating 6; thrust elements 7; dielectric disc with guide vanes 8; electric drive shaft 9; dielectric pushers 10; loading nozzle 11.

The main nodes of the microwave installation (Fig. 1-5) are spherical shielding housing 11, made of two hemispheres, conical resonators with round bases 3 and microwave generators 2 low power. Moreover, along the perimeter of the lower hemisphere there are holes with a diameter of the base of conical resonators. The working chamber is presented in the form of conical resonators 3, the round bases of which are coupled with the spherical shielding body 11. In the upper part of the hemisphere of the shielding body 11, a loading nozzle 1 is installed. When this axis of the conical resonators 3 are a continuation of the radial axes of the spherical shielding body 11. Inside the spherical shielding body 11 coaxially mounted disk 8, rotating from the shaft 9 of the electric drive. On the disk 8 there are guide vanes, and under the disk 8 there are pushers 10. A disk 8, guide vanes, pushers 10 are made of a dielectric material. The blades are located along the radial axes of the disk 8. The pushers 10, in contact with the thrust elements 7, raise the guide plates 4, made of a dielectric material and lower, i.e. Pushers and thrust elements provide vibration of the dielectric tray 4. The magnetrons of the microwave generators 2 are installed at the joints of the spherical shielding housing 11 and the circular conical resonators 3. At the tops of the conical resonators 3 there are discharge openings 5 intended for unloading the finished product. To preserve the radio hermeticity of the microwave installation, the diameter of the discharge opening cannot exceed a quarter of the wavelength. The diameter of the spherical shielding housing 11 and the structural parameters of the conical resonators 3 are consistent with the wavelength.

The technological process of heat treatment of waste slaughter animals in a continuous mode is as follows.

Turn on the disk drive (shaft 9), the chopping mechanism (not shown), which delivers the crushed non-food waste to the working chamber, through the loading nozzle 1, which is on the spherical body 11. Then turn on the microwave generators 2. The raw material falls on the rotating dielectric disk 8 and using the guide blades, due to the centrifugal force is dropped on the dielectric trays 4. In the working chamber (in sphere 11 and in conical resonators 3) the electromagnetic field of ultra high frequency is excited. Raw materials while moving along the dielectric disk 8 and dielectric trays 4 are heated, boiled and disinfected in continuous mode.

When this dielectric trays 4 due to the thrust elements 7 and the pushers 10 are raised to the level of the dielectric disk 8 and lowered, and due to the vibration of the spring 6, the raw material through the dielectric trays 4 moves to the discharge ports 5 and is unloaded into a special container.
